(For a monochromatic plane … Informally, a Fock space is the sum of a set of Hilbert spaces representing zero particle states, one particle states, two particle states, and so on. If the identical particles are bosons, the n -particle states are vectors in a symmetrized tensor product of n single-particle Hilbert spaces H.

There are, however, also interacting representations that are inequivalent to the free Fock representations and that are not of … Webthe second-quantized representation for many-body post Hatree-Fock (HF) theories. In the LCAO-MO represen-tation, each molecular orbital is represented as a linear combination of a set of atomic orbitals. The expansion coefficients of the MOs in terms of the AOs are obtained by solving the pseudo-eigenvalue Fock equation using the SCF procedure.
